`1 use isv made of what is To all whom t may concern:

Be it known that I, RALPH W. WHEELER, a citizen of the United States, residing atl-v.; Brooklyn, in the county of Kings yand State. of New York, have invented new and use# ful Improvements in Wire-Wlieel4`Brushes,

jstitute-nieans whereby the ends of the secof which the following is a specification. y

This invention relates to what is commercially known as wire Wheel brushes, and more particularly to that class .wherein sec,- tions or brushunits are` employed of the desired diameter and weight according to the work .to be performed ,and 'adated to be arranged side by side in brush vorming relation and mounted upon a stock or stand-vv -a'portion ofthe strip showing the manner of threading the bristleforming wires thereard form of hub. y. Brushes of the class referred'to arelargely simplified manner and method of constructing the wire carrying units orsections -of the' brush and the employment of such instru mentalities and certain niceties'of construction whereby thesections or units lcanbe punching the s trip, equi-distantly as. at 2 completely'formed by an automatic operation at a comparatively small cost and with to be punchedat suitable spaced intervals'v to accommodate the .bristle bunches there- .4

through, the bristles being formed by feeding the bristle formingwires along one side"l of the metal stripping and inserting or drawing the same through the punched portions' of the stripping to provide suitable sol bristle bunches, the construction bein such that on a complete feeding of the ristle. wires through one of such strips, the bights of the wire at the terminal of the bristle forining bunches can be mechanically cli ped oli' to free the wire strands and cause t e same to take a brush form,

Another object of the vinvention resides in the provision of metallic stripping hav-- ing.. punched portionsvfor the reception of the bristle forming wires therethrough,l and the provision of marginal portions of the stripping adapted to be upset against the i Srecicatia Oif'LetterS' Iatent- MPatented'Dec. 30,1919.

surfaces of the wire tomaintain an operative retention'of the wire to the stripping. i Another ob]ect of the` invention is to pro- 'videa brush .section formed'of metal with marginal portions up struck to provide brlstle-confimng surfaces and to also contion mayl be telescopically fitted together andthereby c ause thesectionto operatively accommodate itself to `a receiving hub of v.a iven external diameter.

F1g..2- isxa longitudinal section through through. y y i f F'g. 3 is .a section Von line 8-3- ofFi'g. 2. In carrying' the` invention into practice,

commerciallv known as. hoopstripping."i I take a single length 'ofstripping as shown at 5 and in the ymethod or process ofmaking the section,y the "stripm-ay be fed automatically through any 'suitable well known machine which will have incorporated therein a mechanism for so as to yprovide radial 'openings 3 for a purpose to be hereinafter explained" In the ,present'illustratiom the punching is done on a straight longitudinal line but ,in this respect, I of course do notl wish to be limited in that should, itbe desired, the openingsl formed byv this method of punching may4 berelatively staggered or otherwise' arranged.- The punching is performed between the sides of the strip so that the latter will xbe. provided with bendable marginal portions 4 and 5. .Progressivelv with the operation of feeding-and punching the strip,

If feed the bristle forming wires over one side 'of the strip as shown particularly in Fig. 2, passing portions through the open-l ings'v to provide a groupof bristles 6 and I then fold the bristle wires at 7 to provide return bends and then again extend the wires through the openings 3 to provide* 'second groups of bristles as shown at 8.

The connecting bights 9 between the groups Vof Ibristles previously 'referred toare arranged inflat contact withthe inner sur- -tace of the metallic strip as also shown in Fig. 2. After this operation is performed and the strip has been fully provided with forming wir" bend the marginal poitrines; l and 5 over against one another as illustrated in Figs. 3, clenching the saine in close coniinement with the big-his 9 pre- \iouslv referred to. By bendingr the portions l and 3 in this manner, provision is made hereby one end of the strip can be s-ratended telescopically ,into the other end ot thel strip as shown in dotted lines in Fig. l. The strip then assumes the ring torni ,shown in Fig. l wliereby it will operatively accomiiiodaie itseli' with a.. receiving hub ll ot' a given diameter. rlhe ends of the strip may be \\'clded or secured together 4in any suitable well known manner if desired. While the strip is in a straight length. aiter the bristle wires have been fed therethrough, the ends ot' the wires xitly `Yithin the return bends 7 of the respective groups G and 8 can be clipped ott' so as to expose the burnisliing ends of the bristles as will be understood. However, this operation may he. delayed if desired until the section has been arranged in ring t'orin as shown in Fig. l. The entire structure may then be placed under a suitable shearing cutter to eliminate the return bends T referred to.

The rip-setting of the strip to provide the portion '2- is performed. with that regard which will produce within the openings 3 relatively broad curved Vsurfaces 12 so as to prevent possible shearing of the bristles when the brush is in operation.

The openings 3 are arranged with their walls in snug contact with the bristles so as to give rigidity to the bunches and 8 at their juncture with the sti'ip. This con- 'struction gives the proper measure of springiness tothe bristles. combining withI such springfiness a suitable measure of rigidity to permit a highly etlicientburnishing or lpolishing action when the brush is in operation. u

The point in particular of the invention about which Iidesire to lay particular emphasis is the perforating of a stock strip,

nsaaeie preferably oi the kind stated` `feeding the bristle 'wires through the pertorations thus iorined so as to provide normally connected groups of bristles with return bends between said groups and then clipping said return bends to expose the effective burnishin or working extremities ot' the wires. The simplicity of this operation is quite appro-- ciable over tedious and costly operations ot separatelyY bunching or spreading the bristles and applying the 'saine tothe ring. I wish also to lay some stress upon the simplicity of completing the operation ot forming the brush, having in mind the bending over oi. the marginal portions 4 and against the 'bights 9 of the wires. This is an extreinr simple and etiica'cious means for operativi-:ly arranging the strip and the wires in secure confinement with each other.

Vhat is claimed as new is V l. The herein described method of constructing brushes which consists in providing a perforated strip material, threading .a single length of tuft or brush filling inaterial through said perforations to provide outer return bends between the lateral branches, and connecting inner portions between said branches, arranging said inner port-ions against one face of the strip, bending the sides of the strip against said inner portions, and tlienclipping the return bends from the normallyT connected branches of the bristle i'naterial to render said branches rela tively independent.

2. The herein described method of con structing brushes which consists in providing' a perforated strip material, threading a single length of tutt or brush filling Inaterial through said perforation to provide normally 'connected groups of laterally arranged bristles, and then cutting the niaterial at points inwardly of the return bends between said bristle groupsj` v In testimony whereof I have affixed my signature.
